TOVALL TO WHOM 1T MAY Y 'Be it knorvn that We, HENRY POOLEY the elder, and HENRY POOLEY the younger, of the iirm of HENRY Poonnr t SON, of Lverpoo l, in the county of Lancaster; engineers, Tnoiiss RoBsn'rs, of the same place,

iron-founder, and LOUIS LUc,'of the same place, balance-mal er, do hereby declare-the following written speci- -fication to be a full vand exact description of our invention for Au Improved System of Continuous Self- Acting and Self-Registering Machinery for Weighing Grain, Flour, or other Materialsf reference being had to the accompanying drawings', and to the letters and figures marked'thereon, suchand 'alieni-responding letters and figures in each drawing representing similar parts'of the machinery. A

The accompanying drawingsare three in number,- vizi Sheet 1, whichcontains tno figures, Figure lbeing a back elevation, partly in transverse section, with the casing'on that side vremoved to expose the working parts, and Eigure 2 a side elevation, partly inlongitudinal section, with the casing removed as inig. V1. i

Sheet 3 contains, first, Figure 5, which shows the rocking-,shaft with its several fittings, also, part of the 'vertical shaft and its footstep, together with itszconnection 'withthe rocking-shaft, and second, Figure 7,- whichshows the hollow cylindricalbar with its internal adjusting-weight and its extern'al'eompensating-Weight, together with the mode of moving andsetting them, andlof 'their attachment lto the double beams and transverse bars.

We now proceedA to describe and specify'jn detail our invention, thus: The apparatus may best be raised upon a base or foundation-plate of metal, timber, or other suitable material, A A, iigsfl and 2, sheet 1, on and to which all the machinery can be xed,faiid around said'base canA be constructed casing, A2, figs. 1 and 2, -sheet 1, and covering-plates, A3, gs. 1 and 2, sheet 1, wherewith the several Working partsl may be guarded from dirt and injury. A

The working parts of the 'machinery are composed of four distinct sections combined in action to produce the desired result. These several sections are, first, the weighing part; second, the feeding and distributing part`; third, the tipping or discharging part; fourth, the registering part. These several sections we specify in terms `following, viz: l I l First, the weighing part. To accomplish this we make two double beams D, fig. 2, sheet 1, being levers of the iirst order, the short arms of each being one-tenth or other proportion of the length of thelonger arms, each of these double beams forming one casting, the sides being connected by transverse bars EE, iig. 1, sheet 1, and having knife-edged fulcra of hardened steel,f, fig. 2, sheet 1, Working on steel faces dovctailed into eastiron standard B, iig. 2, sheetl. At the shorter ends'of our double beams wemake knife-edge verges or points of impact, d2, iig. 2, sheet 1, upon which the weighing-scales and their attachments rest or are imposed. These Weighing-scales are two in number, III, iigs. 1 and 2, sheet 1, land ranged side by side. -gThey may be best made of sheet iron and of the scoop-shape, iitted'on each of theirsidcs with a pivot, Q, fig. 2, sheet 1, carefully. adjusted in its position relatively to the centre'of gravity, with a view to the mvementof the scale -when loaded,`

and its return to its proper place after discharge.

By means of the pivots, E, here named, each scalerests in the hollowed tops eftwo vertical and cons joined supporters C, iig. 2, sheet 1, the lowerextremities of which 'are lineedinwards and tittedmrith steel faces resting upon the knife-edged verges d?, hg. 2, shectl, beforenamed, at the shorter ends of the double beams. The vertical supporters, non referred to, are kept in their true position-by `means of radius-bars, b, iigI 2, sheet l, equal in length to the zshort arms of the double beams, connected to the vertical supporters near their upper end, and to viixed standards', being prolongations of those'standards B, iig. 2, sheet 1, on which the' fulcra of thedouble' beamsrepose, These rsdiiis-bars are formed with steeled loops at their ends, and are held in tension by knife-edged pivots; 'i i I i i ,At the ends of the longer-arms ofthe double beams D, we, make steel knife-edged centres, from which are freely suspended, by rods, KK KK, g. 1, sheet'1, having steeled loops, scale-plates, JJJ, nge, 1 and 2, sheet 1, `or the reception offtheproportional weights Grl G2, figs. 1 and 2, sheet 1, by which the load of grain or other material is determined, such weights, (provided the. donbloweighing-beams be made of the proportion herein specilied,) being ten pounds to one hundred pounds, or other proportion when the bearns are made otherwise.

The scale-plate J, n ow specified, is perforated in its centre to admit the free passage through. it of a bar or pillar of iron, N N, gs. 1 and 2, sheet 1, which pillar is bolted by a llanch at its foot to the base, above named7 and it is fitted at its top with a cushion, M, figs'. 1 and 2, plate '1,' on which srests loosely the finishing-weight, hereinafter described. i

The proportionahweights Grz and'Gr, gs. 1 and 2, sheet 1, above mentioned, are two in 'number for each scale. Y f 'l Y l A One of each of these two, G1,.is a constant weight corresponding with about eightyper cent. of the total weightof the load of grain or other material to be weighed at one draught.v` This constant weight is placed on the scale-plate J, and similarly Ito that plate is perforated to permit the passage through it of the bar or pillar, above described,'NN, figs; 1 and 2, sheet 1. i i

The second or Jfinishing-weight, G2, figs. 1 and 2, sheet 1, rests loosely lupon a' cushion, M, ligs.'1` and 2, sheet 1, formed on the top of the aforesaid pillar, and it is made with a V-'shaped bead on its under side to lit in a prepared hollow .on the top side of the first orconstnnt weight G1, by .which lesser weight it is caught and lifted as it -rises in Athe act of weighing. The finishing-weight G1 isivariedin `its amount according to the requirements of the different species of grain .or other' material which isto be weighed. "Upon some part of the double beam, and usually attachedto one 'of its transverse bars E, lig. 1,she'et 1, we place a hollow cylindrical mother-shaped bar, Q, tig. 2, sheet 1, paralled to the longitudinal axis of th'ebeam, 'and having within 'it aweight, R, fig. 7, sheet 3, operated by a screw, S, fig. 7, sheet,V 3, with a milled-edge disk, T, tig. 2, sheet 1,`

andg.- 7, sheet 3, 4the use of which is toadj'ust the equilibrium of the scales and otherpats which may become liable to'vary.

A second movable weight, V, tig. 2, sheet 1, and lig. 7, sheet 3, is made yto slide outsidethe samehollow bar Q, which bar has upon its exterioral graduated scale for the purpose of compensating for thesmall portion of4 :grain or other commodity whichis in theact of enteringthe scoop or scale whilst in the'act of tipping.v The second movable weight, now described, ca nbe fixed in its proper place by means of the setscrew W, iig. 2, sheet 1.

As restingsbeds for the longer arms of the double beams, with their scale-plates and weights, we make short A pillars, E F F F, -figs. 1 and 2, sheet 1, bolted at foot to the base-plate,"and in order to preventshocks to the machinery by the sudden fall of the-beams and weights, when the scoops are discharged,w'e tinto thc tops of these `s hort pillars thick caoutchouc cushions, onwhich thc-ends of'the beams are safely received.

` Inorderto limit .the extent of action of thev scoopj-scales'zwhen discharging their load, we'aliix tothe casin A 2, sheet 1, immediatel.. under each scoo a bracket ot' cast iron, F2, havin a cushion atitsg v g c y P g upper end Anpo`n which the scoop falls; lthe position of the scoops when down'upon the bracket being shown on tig;l 2, sheet 1, by thedotted lines.

` Having now described the rst' or weighingsecton of our'saidinvention, we 'proceed-to the second or feed-- ing and distributing part, which we construct as follows: In the centre'ofthe apparatus, between the two scoop scales, we x securely'a hollow upright standard, S S, gs. 1 and 2, sheet 1, 'within which is a vertical freeworking shaft, V S, gs. 1 and 2, sheet 1, resting on a steeled footstep, q, dgl-2, sheet 1. Upon the head of this shaft we t an inclined chute or spout, pigs. 1 and 2, shcct'l, into which the Agrain or'other material to be weighed is directed from the depot or shore, and is by the chute delivered into a small hopper, K2, figs. 1 and 2, sheet 1, ixed immediately below it upon an arm, S, g. 2, sheet 1,w hich is cast upon and forms part of the hollow.upright standard above named;

The small hopper K2, here mentioned, is made with a double-inclined'bottom, forming two sides of a triangle, the apex being -uppermost, which gives the hopper the character of a double chuteor distributer, by which latter name it is in fact distinguished, one passage of which is over each of the twin scales or scoops I I, iig. 1, sheet 1. A I

Now, when the working vertical shaft VS, iig. 2, sheet 1 witli the chute p, is swivelled partially towards ones'ide, more grain will fall into one scoop than the other, and when the said shaft is wholly turned to one side, all the grain will fall into one scale and be entirely cut off from the other. When the shaft is turned first partly and then wholly back again, the I process is reverselhand thus.A each scale is fitted alternately. i The hopper or 4distributer K2 is ttcd ona saddle upon which 4it can be moved by a screwand hand-wheel, @nearer or further from the centre of the scoop', as circumstances require.

Just above the'footstep g, s heet`1, ot` the vertical shaft, is iitted with ahorizontalbar or arm, nb, g.v2, sheet 1, the end of which takes into aA slot formed in a. vertical arm or bar, 1, fig. 5, sheet 3,- which latter arm is keyed or otherwise secured to a horizontal rockin'gfshaft, vX, g. 5, sheet 3, and tig. 2, sheet 1, working on stationary bearings, and lying between and parallel Ato the double or weighing-beams.

At and upon the rear or inner end of the said'rocking-shaft is litted a lever, Y, fig. 5, sheet 3, and Y, fig 1, sheet 1, in the form of an inverted T or L, the transverse lim'os of .which T-lever extend over and across the inner halves of each of the double beams, andare ben't downwards as tappets approaching towards tableheads Z Z, iig. 1, sheet 1, of adjustable screws fitted in the transverse bars E E of Vthose double beams.-

For the purpose of sustaining thebearings of the rocking-shaft, two standards, L S, figs. 1 and 2, sheet n1, are firmly bolted to the base-plate, A, one of which standards is continued upwards and gives support to the registeringapparatus hereafter to be described.

Upon this last-namedstandard laretltted two balanced catches, b Zin-tig. 1, sheet 1,A one for each scale, lying i horizontallywhen at rest, and embracinga square stud formed upon the vertical limb of the inverted T-lever Y, iig. 1, :and from the tail of each of these catches there hangs loosely, from a joint, a rod, C C, fig. 1the -lojverend of which rod approaches, within'a regulated and adjustable distance, the top 'side of cach ofthe transverse bars E E, igfl, of the doublehearns. I I i The action of the several parts of the feeding and distributing arrangement now specified is the following: Whenahout eighty per centof the load of grain has been rcceivcd'into one of the scoop-scales, itcauscs the longer-,arm of one-of the double beams D D, and the first orconstant weight G, figs. 1 and 2, sheet 1, to risc as high as the second or finishing-weight G2, figs. 1 and 2, which reposes on the hea-d of the pillar N, centra-1 to the scalo-plate J, and, in rising, the tablc-hcad Z Z, 5g. 1, of the, screw upon the double beam `comes in contact with and lifts one of the t-appets of the inverted T-levcr Y, iig. 1,'by which it turns the rockngshaft X, iig. 2, sheet l, and with it the vertical shaft V S, fig. .2, and swivelling-spout or feeder p, tig. 2, are turned partially towards the second scoop-scale. i i

Whenthe fullprescribed load hasbeen delivered into the vfirst'scoop-scale, the double beam again fur- -ther rises up to and lifts the finishing-weights G2, figs. 1 and 2, sheetl, and in `its rise touches the end of the hanging rod C, fig. 1, which lifts the tail of the catclrb, 1, and libcrates the inverted T-levei Y, which then completes its action upon the vertical shaft X, fig, 2, sheet l, and sw-ivelling-spout p, iig. 2, thereby shutting olf the entire feed of grain from thc'iirst scoop-scale, and turning the full delivery into the second scoop,

the process going on from scale to scale continuously. `:[t preferred, in place of using the swivelling hopper` spout hereinbcfore described,a double-spout, F F, tigri), sheet 2may be fitted on the under side of thc supplyhopper E, fig. 9, sheet 2, and which is divided into two parts at the throat or upper end by a vertical diaphragm, asshown inthe drawing. By'this double hopper-spout being thrown on one side, the supply may b'e given into either scale, or, by being partially thrown on to one side, a larger supplyymay be given to one scale than to the other; but if the dividing-diaphragm in the throat of the rocking-spout be brought toa vertical position,

the supply to cach scale will be equal. This double spout may be actuatedjfrom the horizontal rocking-shaft,

hereinbefore described, in any convenient manner. v

The third or tipping and discharging section of. our said invention'is constructed in the following manner; i The scoop-scales I I, figs. 1 and 2,-sheet 1, rest, by means of their pivots Q hereinbefore'deseribed, upon the superior ends of their vertical supporters C,.{ig. 2, each being "retained in thc position most suitable for receiving the loads of grain, by means of a stud, BX, fig. 3, sheet 2, riveted to thebottom of each of the scoops, which stud lies within a recess in a catch, AX, fig. 3, sheet 2, working on a. pin, C, fig. 3, sheet 2, secured to ope of the above-named-vertical supporters, c, tig. 3, sheet 2.` Each catch, AX, has one of its ends prolonged,v

and to that end is attached a rod, Z B, fig. 3, sheet 2, connectingit with a trigger, X W, fig..3, sheet 2, which works freely on a pin, T P, iig. 3, sheet 2, secured to a lower part of'the same vertical supporter c at a vlevel somewhathelow that of the horizontal rocking-shaft-X, fig. 2, sheet 1. Uponthe rocking-shaft X is keyed, or otherwise secured, a short upright bar, r, iig; 5, sheet 3, slotted at its upper end, andinto this slot we put the shorter end of a horizontal-kneed lever, s Z,iig. 5, sheet-3, lyi'ng parallel to and above the rocking-shaft X, and working on a pivot-fulcrum,pf, igf, sheet 3, lixedupon the top of a short pillar, which carries one bearing of'the said rocking-shaft'X; on which pivot-fulerum it is movable freely. The longer end of this kneed lever s Z takes loosely into a tumbling-hammer, U, tig. 5, sheet 3, V-shaped interiorly,iu u, iig. 4, sheet 2, which hammer is fitted upon thepart ofthe rocking-shaft which lies immediately between the two triggers X W, g. 3, sheet 2, before specified, and it has action lateral-ly both ways, but limited in its extent by a transverse slot, t s, iig. 5, sheet 3, in the hammer U, anda pin tted in the rocking-shaft.

The hammer is weighted at its 'topvAT W, fig. 4, sheet 2, to such an amount as-to cause it, when moved from its place of rest by the action of the horizontal levers Z, iig. 5, sheet 3, to tumble or fall upon the upper side of the trigger X W, which it depresses by its pallets p d, iig. 4,' sheet 2, and thereby withdraws the catch from the stud BX, tig. 3, sheet 2, on the bottom of the scoop-scale 1,' which then immediately tips and discharges its load. The trigger XW is fitted with'a rule-joint R J, tig. 3, sheet 2, which allows it to yield to the hammer in its return action. v

We must observe here that the same leading movements which operate the'feeding and distributing section of our invention actuate the tipping and discharging part; also saving in so far as we specify under the latter designation separately.

It now remains for us to describe the self-registering section of our invention, or fourth part of the specification, as follows: Upon the head of the standard, before described, L S, figs. 1 and 2, sheet 1, which carries one end of the rocking-shaft X, and other parts before described, we fix a. cylindrical counter, 4 3 2 1, fig. 1, sheet 1, having as many free concentric Arings as there are places of figures in the ultimate result of a. given period of weighing-action. To each end' of the axis of the counter, we key a slotted lever, 2, fig. 2, sheet 1, and to each of these levers we attach one arm of a two-armed or bellicrank lever, L, having on one arm a stud taking into the slot z, same figure, and, byv its other arm, resting against o nc 'end of a horizontal connecting-rod, e r, fig. 2, sheet 1, the other end of which rod is jointed to a part of the scoop-scale in such manner that each time the scoop falls in the act of tipping its load, it pushes the connecting-rod against one arm of the bell-crank lever L, and by its agency operates one of the aforesaid slotted levers, and thereby' moves the counter one figure correspondent with the number of the load which has just been weighed and discharged. n

This self-registering apparatus now described is enclosed within an iron or other casing, A, figs. 1 and 2, sheet 1, which defends the several parts from injury and from dirt, and this` case we prefer to have under lock,- in order to'prevent-the indication being tampered'with, but we provide that part of the said casing' shall be' composed of glass in front of the movable '.conccntric rings or disks, as at C G, tig. 2, sheet 1, so as to render visible the progrcssand results of the apparatus toi'the .person in charge. i

Tn describing the mode of action of our apparatus, it isneccssary to premise that the several movements by which the Weight is ascertained, the feed distributed to t'lic scales, or the load discharged therefrom, and the duty of the machine registered, are operated entirely by the momentum due to the load of grain or'other mate. rial which is being weighed. The'process is -carried on in the following manner; that is to say, the grain is introduced to the machine from the-depot in any manner by which a continuous supply can be conveniently delivered into the feeder. Then, when the `first scale has received the main part of its load, that scale falls thlougha portion of its full descent, and, in falling; lifts a proportional weight equal to the partial load then in the scale, 'and at the sarne' moment moves the distributor partly toward s' the second scale, which then begins to fill, irhilst the first scale is'receiving more slowly vthe finishing part of itsload.` When the load is complete in one scale, that scale falls through the remaining part o'fits descent, andin falling'releascsl-thc catch-that, till then, had held it in position,-\vhereup on the scale immediately tips, and simultaneously. shifts the full feed of grain over the second scale, at same time moving theregister one figure, showing the number of the load then rveighedQ l i v l rThe operation proceeds from scale to scale alternately as long as the feed of grain is continued, and is entirely self-acting throughout, the flow of grain or material never being cut off-or `interrupted during the discharge of the scales, wl'iicltwe believe toy be an advantage not heretofore successfully accomplished by any other apparatus. i l A i Having new fully described and set forth the nature of our invention, and'how We believe the same may be best carried into practical effect, we wishlit to be. understood that Wedonot conine ourselves to the; precise details, relative proportions, or dimensionshereinbefore particularized, as it may bc' readily seen that the same may be considerably variedwithout departingfrom the invention; but v 1.
